Among the features in the new version, according to Mike Beltzner, Mozilla's director of Firefox, and Mozilla evangelist Chris Blizzard:

 Personas, which lets people customize the browser appearance. Personas has been available as an add-on, so there are plenty of Personas skins to choose from.

 Faster execution of Web-based JavaScript programs, better browser responsiveness, and faster startup time. Mozilla has been working on JavaScript performance for many months, but the urgency of that and other performance improvements increased with the arrival of Google's Chrome browser.

 The ability to drag and drop files from the computer to the browser. This is useful for uploading files to Web sites, as will a feature not in the beta but planned for the final version, support for the multiple-file input tag so more than one file can be added in Web forms.

 Expanded support for geolocation technology so it can provide a Web site with an approximate physical address of the user, not just latitude-longitude coordinates.

Firefox is at the vanguard of the second generation of browser wars. Although it competes with Google's Chrome, Apple's Safari, and Opera, all those browsers are also allied in a way against Microsoft's Internet Explorer, which though dominant is relatively slow at some tasks and only now complying more fully with Web page standards of yesteryear. The rivals, meanwhile, are pushing ahead with new features in HTML5 in development right now.
